This video is hilarious, and the song's not too bad, either. It's by the guys that did the "Things You Can't Do When You're Not A Dog" video. This one features Chris Tomlin. Enjoy.
And if that's not enough, check out Jay's short story he's been adding up on Fridays. Today is Part 2 of 5. Both have been very entertaining.
And if that's not enough, check out a book of mathematics proofs from the library and dive into the deep complexities of understanding formulas and the like. Just for fun, try proving the cross-sectional area of a circular pipe that's not quite full.
And if that's not enough, sell all your belongings and move to a monastery in Tibet. Bring a telescope and set it up out in the middle of a big field at night, away from all artificial light, high up in the mountains, and stare out into the deep black of space. Contemplate your existence while peering millions of miles away.
And if that's not enough, stay out there until daylight and look at the sun with your fancy telescope. That'll surely be enough.
I'm ready for vacation... my brain's fried.
